Yeah we aren't using bait. I don't want this place stinking. I haven't noticed mice upstairs. We have kids and they leave stuff out, plus our pantry has cereal boxes on the floor. No signs yet. I'm hoping they don't make their way up here. I've got 6 traps set right now. If I catch a couple more I'm calling the landlord and getting an exterminator out here.

Just make a cursory check of your basement to look for any potential entrance for these little little guy's, if you question a specific area put your trap against the wall in the immediate area to see if you get any 'action'
